NAME
UNIVERSAL::exports - Lightweight, universal exporting of variablesSYNOPSIS
package Foo; use UNIVERSAL::exports; # Just like Exporter. @EXPORT = qw($This &That); @EXPORT_OK = qw(@Left %Right); # Meanwhile, in another piece of code! package Bar; use Foo; # exports $This and &That.
DESCRIPTION
This is an alternative to Exporter intended to provide a universal, lightweight subset of its functionality. It uses Exporter::Lite, so look there for details.Additionally, "exports()" is provided to find out what symbols a module exports.
UNIVERSAL::exports places its methods in the UNIVERSAL namespace, so there is no need to subclass from it.
Methods
UNIVERSAL::exports has two public methods, import() derived from Exporter::Lite, and exports().- import
-
Some::Module->import; Some::Module->import(@symbols);
This is Exporter::Lite's import() method. Look in Exporter::Lite for details.
- exports
-
@exported_symbols = Some::Module->exports; Some::Module->exports($symbol);
Reports what symbols are exported by Some::Module. With no arguments, it simply returns a list of all exportable symbols. Otherwise, it reports if it will export a given $symbol.
DIAGNOSTICS
- '%s is not exported by the %s module'
- Attempted to import a symbol which is not in @EXPORT or @EXPORT_OK.
- 'Can\'t export symbol: %s'
- Attempted to import a symbol of an unknown type (ie. the leading $@% salad wasn't recognized).
